I've probably used it more than a hundred times (I tend to try a lot of utilities just to see how well they work) and it has never caused any problem. Some few entries may have been set to delete during reboot, but most are simply orphans. Revo routinely finds files, folders and registry entries that have been left behind. I'd have to disagree with Turbo at this point. After that is finished, Revo does its own search for garbage left behind. As Turbo indicated, Revo first calls the normal uninstall routine for the software being removed. I've used Revo Uninstaller for quite some time.
I just wondered if anyone has tried the revo uninstaller (No, I'm not planning to use it to uninstall norton).
